T0 all whom 'it may concern: v

l .Be it known that We, ERNEST FERRAN and FRANCIS D. TWEEDDALE, citizens of the United States, residing in the city and county of San Francisco and State, of California, have invented a new and useful Improvement in Call-Registering Devices for Telephones, of which the following is va specification. i

Our invention relates to registering de- .vices for telephones wherein the electrically operated mechanism in nickel telephone boxes operates mechanical means for registering the number of switches. obtained through the telephone to which the said nickel boX is connected, and the objects of our invention are first, to provide improved means for registering every switch or connection which is made through the telephone to which the device is connected; and second, to provide improved means for regis; tering calls Where the desiredA connection or party is not obtained. XVe accomplish these features by means of the device illustrated in the drawings forming a part of the present specification, wherein li re characters of reference are used to designate similar parts throughout the` said specification and drawings, and in which* Figure l is a view of nickel collecting boi: for telephones With thei front portion thereof partly broken away, disclosing the registering disks rotatable in opposite directions, the armature which operates one of the disks, the spring ContactA which engages the token which is being returned to the subscriber, and the springs which retain the armature normally in a centra-l position. Fig. 2 is a side view of the nickel box with .the side thereof and the innenplate removed,

disclosing the arresting pins projecting through the frame, and the slot pressed Within Vthe said fra-me. Fig. 3 is a detailed broken view of the armature' and the springs Which normally retain it in a central position. Fig 4 is a horizontal sectional view through the nickel box disclosing vthe arrangement of the coils and armature for returning the token to the subscriber or into the box, and operating one` of' the-registerthe coil and armature for operating the refund registering device. Fig. 5 is a vertical sectional vievv taken on line X-X or' Fig. 4 d isclosingthe manner in 'which the registering dis s are rotatably.

y and slightly beyond I end attracted will vents a return movement ofthe refund registering mechanism. Fig. 7 is a broken detailed vieW of a portion of the registering disks and the Window in the front oi the cover of the box..k Fig. 8 is a diagrammatic view of the electrical circuit for operating the various parts of the device. n

In telephones Where a nickel or token box is used, theonly means by which the number of switches obtained may be determined, is by the number of 4token'in the bex. Subscribers have discovered and 'invented various means of obtaining switches and operating the signals at the central station without using tokens.

In the present equipment, a is provided with a cover 2 having an upper slot 3 through which the nickel or token Vv is inserted. The frame 4.- secured to the lbase plate l and Within the cover, 2, is provided With the impressed slot fhaving the inclined receiving portion 5, the curved passage 6' and the inclined return -or refund portion 8 through whichy the token V is delivered through the lovver slot 9 .of the cover 2 and into a suitable, receptacle 10. The frame 4c is also provided with an aperture base plate or. collecting portion?v through' which the the frame 14 and the frame t. The lower ends of the springs 19y and 20 rest on the edge of -the bearing 17 the upper edge of the armature 16 so that when the said armature is operated by either coil l2 or 14 the engage the spring on that side and be returned-to normalposition by.

fthe said spring as soon as' the said coil is denergized.

Pins 24 and 25A are. secured to the arina-` ture 16, the pin 125 being insulated therefrom, and project through apertures in the curved ortion 6 of the: slot in the frame 4 in suc a position that a token, of the 'cor- 'jrect size and shape in the said slot, will be retained by the said pins 24 and 25.

In the present state of the art when the party using the telephone desires to attract the attention of the operator for the purpose of making the desired connection, a token V is de osited in the slot 3 of the 'cover 2 and ro g. down theinclined portion 5 is delivered between the pins 24 and 25.

By referring to the circuit in Fig. 8 of i the drawings, 'it will be observed that the the` proper connections are made to the party desired which 'have no connection with the present invention andare conse- .quently not shown. If the desired conneCr' tions are `.obtained 'by the'calling party, the operator passes the key and 'connects the Vsamefwth the battery 36. Thecurrent will, then flow from thefsaidfbattery 36 through' ythe said key' 35,'line 37,` line A30, coils 14 and 12, line 33 to the frame land to the ground, The current flowing inthe above direction will cause the coil 12 to act on that lside of theoscillating armature 16 and Withdraw the pin 24' whichY will allow the token V to drop intoV the collecting portion of the slot on the inclined slide 40 ofthe cover ,piece 4l which inc'losesthe slot"v impressed within .the frame 4, through the slot 7 into the cash fbox'within the vcover 2. SeeFig-f 1 of the drawings. Y

ifWhile the 'current battery 27 is .45"

suflicient to'light ,the lamp 29 it lis not surfi-4 cient tofoperateeither coil 12 or 14.

If the` pargty sought is busy or the connections vfor'any reasonv not obtained, the op-A erator moves the vkey 35 to the opposite di4 rection land into contact with `battery 36 lv vhich causes the current to flow in the oppo` f 'site'` direction` from4 that heretofore describedwhen the token islto4 be deposited in the cash box. The current will thenxllowY through the hereinbefore mentioned lines and inem-Y',

p bers and .cause the coil 14 to attract the armature 16 ,on that side, therebv withdrawing the insulated 'pin' -25 and allowing the tonen Vto 'dropr into the linclined .portion 8 of the slot inthe frame 4 which vwill deliverr the said token'through the lower slot 9 inthe .cover Land-intothe receptacle 10`thereon .fromwhich it may be recovered by the per-l son who deposited it.

' Thus far the description of the operation 1 i v i prevent a return movement 'of ratchet 46. l i

By referring to Figs. 1 and 4 of the drawA movement will, by meanslof the has referred to the present rnethodof registerin the number 0f calls or switches obtaine from anyone telephone.

Referring to the circuit in Fig. 8, it willA be observed that ifthe subscribers end of the line 1s grounded through the token box, f

`which to determine Whether o r not a proper token has been deposited, and if there is no token betwen the pins, no token will be collected. to register that switch. y

We propose to provide means whereby every switch called for will vbe registered Whether obtained or not.

for registering such refund. The total number Vof switches registered minus the refunds registered will` then indicate the number of switches or 'calls obtained except when the signal Vat the central station has been operated by other means than the deposit of a suitable token and the party is not 0btained then the central operator in operating the tokenrrefun'ding mechanism' will register a switch obtained. The above means to Lbe operated by the coils and the armature which are'faty present used for the pur-y pose of collectinggor returning the token.

We have' provided an insulated extension 22 to the armature '16, said extension 22 be- If the desired` `switchis not obtained the passage of the refunded coin will electrically connect means ing pivotally connected to a rod 42and the disk 47 on the shaft The upper end'of the lever 43 is provi'ded with a suitable pawl 45 which engages the teeth of the ratchet 46 secured to the disk 47. A pawl 48, pivot,- ally secured to the frame 4, is adapted to the said ings, it will be observed that when the armature 16 is attracted by either the collecting coil 12 or the 4refunding coil 14, the said awl 45 and the ratchet 46, cause the registering disk 47 to be advanced one number. A refund registering disk., 50, having a smaller 'diameter than thedsk 47 Icofncentri"c therewith,

isri'gidly secured' to lthe front end of thev shaft 44 while aratc et 51 is secured to the other end thereof, said ratchet ,51 vbeing adapted to be engaged ,tbya pawlf2, on the upper vend of 'ariecond lever loosely mounted upon the shaft 44, and/s adapted tc beV rotated by itspawl 52 in the opposite direction from 'that in which,the disk 47 rotates, the purpose of which ifs, that when-130 each end of the armature and projecting into the slot Within the frame, one of the said pinsbeing insulated from the said armature; suitable coils arranged to attractthe armature and to Withdraw one of the pins; and registering means operatively connected to the said armature and arranged to register each movement of the said armature.
